Trends and developments of renewable energy projects for electrical energy production with emphasis on wind and solar energy

European Union directives, as well as the current legislation of the Republic of Croatia encourage the use of renewable energy sources. To make this increase happen, it is necessary to develop the market, which in Croatia, as well as other EU countries started to develop more intensively after the introduction of legislative framework for the production of electricity from renewable sources. The adoption of Update/upgrade of the Energy Strategy of the Republic of Croatia set even more ambitious goals of using energy from renewable sources. Continous development of wind energy market has taken place in Croatia since commission of first wind farm Ravne I on island of Pag in 2005. Current cumulative installed power of wind plants in Croatia is 89 MW. According to data from the Ministry of Economy, Labour and Entrepreneurship, there is a large number of ongoing projects: 144 projects with total power of 6489 MW has achieved Preliminary energy approval, while 11 projects with total power of 175.35 MW has signed Power purchase contract. This paper will give detailed overview and analysis of wind projects according to various criteria (location, installed capacities, involved companies, market shares etc…). Solar energy represents the energy resource that is not yet fully used, although Croatia, especially the coastal part, has a good potential of solar irradiation. Besides the installation of individual solar thermal collectors and small photovoltaic plants on roofs of residential houses, only a several projects using solar energy to support the heating/water heating has been realized and no larger photovoltaic plant has been realized. Few larger photovoltaic plants are in early development phase. This paper will give overview of current commissioned projects, as well as overview of possible future projects regarding use of solar energy in photovoltaic systems.
